I used to avoid running locate/slocate entirely due to disk thrashing.  More 
recently I've started using mlocate, which is similar to slocate with the 
addition of a timestamp database, so it will ignore any directory trees that 
haven't changed since the last update.  Since it doesn't need to scan the 
entire FS every update, it runs much more quickly with much less thrashing, 
so you can update far more frequently.
